Definitions

  • the invention relates to a system of a recordable medium and a recording apparatus for recording programs on the recordable medium, a recording apparatus for use in such a system, a recordable medium for use in such a system, and a method of recording.
  • the invention is particular relevant to a DVD-recorder.
  • US-B-6,243,353 discloses an optical disc which may be dedicated to recording a specific program.
  • the recording reservation information necessary to perform the recording reservation comprises a variety of pieces of information, e.g., the program name, the recording period, the recording time, week information, and channel information.
  • the recording reservation information is written on the optical disc. This is a quite inflexible approach, the specific program will only be recorded at a daily or a weekly rate during the time period indicated and received at the channel indicated.
  • This prior art approach does not allow the user to record a specific program independent on when it is transmitted and on which channel or via which medium it is transmitted, unless the user provides a large amount of recording reservation information taking into account all the channels on which the specific program is available and taking into account the respective times the specific program is available on each of these channels.
  • a first aspect of the invention provides a system of a recordable medium and a recording apparatus as claimed in claim 1.
  • a second aspect of the invention provides a recording apparatus as claimed in claim 3.
  • a third aspect of the invention provides a recordable medium as claimed in claim 12.
  • a fourth aspect of the invention provides a method of recording as claimed in claim 16.
  • Advantageous embodiments are defined in the dependent claims.
  • the system in accordance with the invention comprises a recordable medium and a recording apparatus.
  • the recording apparatus comprises a receiver which is able to receive a plurality of programs. Usually, the receiver will be able to receive one of the plurality of programs at a time.
  • the receivable programs are all the programs or a subset of all the programs which the receiver is able to receive. For example, when the programs are TV- broadcasts which are modulated on high frequent carriers to form a high frequency band of TV-channels, the receivable programs are the programs available at the channels which the receiver is able to receive.
  • the plurality of programs may also be comprised in a digital data stream. The data stream may provide different programs at a high rate serially in time, or as short interleaving packets.
  • the recording apparatus further comprises a comparator which compares program information on the receivable programs with the search instruction recorded on the recordable medium. For example, the receiver checks the receivable programs on the search criteria one by one by selecting the TV channels cyclical and retrieving program information for each selected TV channel. In another example, the program information on the receivable channels is present on a specific TV channel, or in the data stream. If the comparator detects that the program information of a particular program matches the search criteria recorded on the recordable medium in the recording apparatus, this particular program will be recorded on the recordable medium. Programs of which the program information does not match the search criteria will not be recorded on the recordable medium.
  • the recordable medium comprises a recorded indication of a specific type of program which should be recorded on this particular recordable medium.
  • the comparator detects whether one of the receivable programs matches the specific type of program which should be recorded.
  • the comparator controls the recording unit to record one of the receivable programs on the recording medium only if it matches the specific type of program which should be recorded.
  • the recording apparatus is a DVD-recorder which has a tuner for receiving TV-broadcast programs.
  • the user has to insert a recordable or re-writable DVD-disc on which a search criterion is recorded.
  • this disc is labeled by the user as a news disc.
  • the recorded information on the disc only indicates that the type of program to be recorded is news. Thus, there is no information on the disk about the time or channel the program occurs.
  • the recorder will have to search whether the type of the program to be recorded is available in the receivable programs.
  • the program information may also be available as program specific information in DVB, Gemstar program information, Nextview, or the extended data services of close captioning.
  • the recorder will automatically record all programs which are detected to be of the specific type, in this case news, independent on the channel or time the program occurs. The user has to perform a minimum amount of effort to obtain a maximum flexibility in recording a specific type of information. Further, the management of the record mediums is very simple as this particular record medium can be labeled with a fixed label indicating the specific type of program.
  • US-B-6,212,327 discloses a computer which receives an information stream which may comprise the current contents of selected TV channels. The computer may be instructed by a user to have programs recorded whose description in the information stream contains keywords such as "Cary Grant" or "basket-ball". The computer searches for these user-selected keywords in the data stream.
  • the computer formulates instructions for controlling the record/playback device to record a program associated with the key data item. Then the computer waits until the start time of the associated program to send an IR command to the separately arranged record playback device to start recording the program. When the program end time is reached, the computer sends an LR command to the record/playback device to stop the recording.
  • the computer may obtain the program data from a data stream originating from a server or from a computer readable medium on which this data is recorded.
  • This prior art does not address the management of the record medium to be present in the record/playback device.
  • the record medium has no recorded information on the type of program to be recorded, a high discipline of the user is required to have the correct record medium inserted in the record/playback device. If a specific program is recorded, the user should easily be able to identify that on this particular disc the specific program is recorded. This is especially important if the record medium is a rewritable medium on which successively many programs can be recorded. Further, the user should check whether sufficient free space should be available on the disc inserted. Otherwise another type of program may be deleted to enable the recording of the specific type of program.
  • the optical disc disclosed in US-B-6,243,353 comprises recording reservation information which is a complete set of information (program name, time, date, channel) required by the recorder to be able to record a specific program.
  • the data on the optical disc is not a search instruction but a record command.
  • the recorder will not search for programs matching the search instruction but simply record the program as commanded by the record command.
  • the program data available in specific TXT pages is used. This has the advantage that the information on the receivable programs can be easily extracted from the programs received without the need for extra connections such as via internet or by phone to get the information on the type of programs available on which channel at what time.
  • the recordable medium is a re- writable medium. If insufficient free space is available, the oldest recorded program(s) are over-written to make sufficient space for the latest program to be recorded. Usually, this is not a problem because this particular recordable medium is dedicated to one particular program only. The user will not lose not related programs, and it is very likely that he has consumed the oldest recorded program(s) already, or is interested in the latest program only.
  • the recording apparatus comprises a further recordable medium which may be a hard-disc, a solid state memory, a tape or any other medium suitable to record programs.
  • the removable recordable medium can be used to record on the recordable medium the programs as indicated by the search instruction, both as available on the further recordable medium and as available in the programs received. In this manner, also the particular programs matching the search instruction which programs are already recorded on the further recordable medium will be recorded on the removable medium.
  • Such a removable medium enables to transport the recorded programs of the particular type to other locations.
  • the recordable medium is provided with a visible marking indicating the search instruction recorded on the recordable medium.
  • This allows selling recordable mediums which are marked in accordance with the information which will be recorded on the recordable medium. It is especially interesting to sell a set of recordable mediums, each one for recording another type of program, and each being visually marked according the type of program to be recorded.
  • a set may comprise recordable mediums for news, weather, football, sports in general, a particular soap series.
  • the visually marking comprises an image representing the type of program.
  • the user now has an extremely simple way of managing his recordings. The user simple inserts the recordable medium marked with the type of program of interest and the recording apparatus will record this type of program as long as this recordable medium is inserted in the recording apparatus.
  • the recorder warns the user if this is the case.
  • the user may indicate whether it is allowed to overwrite earlier recorded programs or not. If not, the same procedure may be followed as for record-once mediums. If yes, the disc will automatically write over older recorded programs and thus will contain the programs of the specified type which are received the latest. Usually, this suffices the needs of the user, which has already consumed the older recorded programs.
